With a calc in the hand and many hours with HexEditor i found the start of the data on 1,2,3 disks...Obviusly the data start it's not the partition start.. i established that first 10mb of disk 1 2 and 3 was zero filled... (i don't remember indexs but i'll post all my tables tomorrow)

I made same partition table for all 4 disk, cloning the structure of 4th: 2Gb 997Gb1) /dev/sda1 /dev/sda22) /dev/sdb1 /dev/sdb23) /dev/sdc1 /dev/sdc24) /dev/sdd1 /dev/sdd2Finded old dumps of mdadm i rebuilded the RAID5 from the NAS with SSH...mdadm --create --assume-clean ecc...

I obtained a readable volume of 2.7Gb.. Mounted the RAID5 on PartedMagic..

checked with photorec and i obtained 15mb zip archives and a lot of big jpeg so i can say that RAID work very fine..

Now...Searching the partition...{... skipped all my mental masturbations on LVM group that i resolved with a loopback from the offset that i find in the system partition of the nas...}

I know that, the partition is an XFS, i found the start of the superblock It was on 4th disk but... :'Recovering and trying with many programs, forcing the xfs_repair -L and ecc.. i can see only few file, that are intact, but i can't find my ISCSI disk of 5Gb... i found another disk of 100Gb but it's not what i want..In addiction the internal data of Virtual ISCSI disk make my life terrible with a RAW recovery...So any suggestion?Is there a method to restore lost XFS inode? Knowing the start of my ISCSI Disk, can i copy it contiguously?
